When duplicating a chart/question, it creates a shallow copy of the original so that when I make changes to the copy, it also changes the original, which means I never use the Duplicate function. Not sure what others think, but it would be far more useful if it created a deep copy instead so changes were distinct from the original.
Currently, if I want to create a copy with changes, I need to edit the first chart, then save as a new question, then re-connect all the filters, which is inefficient.
